�A -29 DRAFT URBAN WATER MANAGEMENT PLAN 9.09 MGD to the SBSA treatment plant. SBSA is a joint powers authority, of which the City is a member that provides service to the City, Belmont, San Carlos and the West Bay Sanitary District. The SBSA is responsible for operation of four pump stations, one force main and a sub - regional tertiary wastewater treatment facility, located at the eastern end of the Redwood Shores peninsula in Redwood City. The SBSA is permitted by the Regional Water Quality Control Board ( "RWQCB ") to discharge wastewater into San Francisco Bay. 2.2.2 Current Use of Recycled Water The RWQCB, when approving permits for SBSA's expansion project in 1997, required SBSA to participate in developing a pilot water recycling project. Working with SBSA, the City initiated a "First Step" recycled water project in 2000. This project, which has been in operation since May, 2000 initially provided recycled water from the SBSA plant to irrigate eight landscape sites (median strips, parking strips, greenbelts and parks) owned by the City plus a 20 -acre landscape impoundment owned by SBSA. In 2001 the project was expanded to extend service to private sector customers at the eastern end of the Peninsula, taking advantage of the dual water piping facilities that were installed in the streets as part of residential and other development since the mid 1980s. These customers include one planned residential apartment development and one commercial development. All use of recycled water is for landscape irrigation and landscape impoundment. During the 2002 irrigation season, the City distributed nearly 24 million gallons to these customers. Currently the First Step Project is permitted by the State of California Department of Health Services (DOHS) for operation through 2003. 2.2.3 Potential Use of Recycled Water The City commissioned two engineering feasibility studies of expanded use of recycled water, both of which were completed in 2002: ❑ Water Recycling Feasibility Study for the Redwood Shores Area, by Kennedy /Jenks Consultants, January 22, 2002. ❑ Water Recycling Feasibility Study for Redwood City, by Kennedy /Jenks Consultants, August 7, 2002. The second report addresses alternative projects ranging from one limited to certain customers in Redwood Shores only (1,100 AF/Y) to a city -wide project serving a broad class of customers (3,172 AF/Y). The report identifies a project involving two areas east of Highway 101 (Redwood Shores and Greater Bayfront) with an estimated demand of 1,955 AF/Y as the most cost effective alternative. A copy of the Executive Summary of this report, together with a map of the recommended alternative, is attached as Appendix F. The great majority of forecast use of recycled water is for landscape irrigation, with some potential for industrial users identified in the Greater Bayfront area. 19
